ABSTRACT

OBJECTIVE To explore the efficacy of autologous fat injection of eustachian tube pharyngeal orifice in the treatment of Patulous eustachian tube (PET). METHODS We selected 18 patients who had no obvious improvement after medical treatment of PET over 1 months. They were treated with autologous fat injections to narrow the pharyngeal ostium of the eustachian tube. The treatment results were documented, including the patient's supervisory feeling and visual analogue scale (VAS). RESULTS The total effective rate was 83.3％ after 12 months of follow-up (symptoms significantly reduced in 27.8％ of patients and partial improvement is 55.6％), 16.7％ the symptoms remain unchanged, no one worsened. No patients had any complications. CONCLUSION Autologous fat injection of the eustachian tube is a effective and safe treatment for PET with the percentage of significant or partial relief of 83.3％, It is easy to conduct in clinical practice which could potentially serve as an alternative treatment for PET.
